The uptake and whole-body retention of /sup 32/P and /sup 65/Zn was studied in subjects whose diet contained measured quantities of Columbia River fish. The /sup 32/P and /sup 65/Zn content of duplicate fish samples was measured. An instrument developed for measuring /sup 32/P in vivo gave good agreement with whole-body counting data. Preliminary results indicated that all subjects absorbed more than 95% of the /sup 32/P available in the fish while /sup 65/Zn absorption ranged from 31 to 50% of that available in the fish. The effective half-life of /sup 65/Zn was 150 days. There appeared to be greater variation in the metabolic parameters of fractional absorption and effective half-life in the case of /sup 65/Zn than was apparent for /sup 32/P.
